Matrix Flooding

The Seabox™ subsea water treatment unit can be used in combination with microfiltration to tailor water qualities to suit the reservoir needs and especially to provide particle-free water for matrix flooding. After the Seabox™ unit has disinfected the seawater and settled out major sediment parts, the microfilters can be added to remove all remaining particles. The microfiltration is a ‘dead end’ filter, which will remove all particles down to 0.1 micron.

The microfilters are cleaned with back flushing only and no chemicals necessary. The Seabox™ subsea water treatment unit and microfiltration are controlled by Seabox’s Subsea Control Module (SCM), an ‘All Electric’ solution. This gives a unique control of valve operations and filter performance.
